Compatibility & fit

This is a generic M12x1.0 rear bolt-on replacement, not tied to one bike brand or hub standard — the frame's thru-axle bore has to be the right length and thread, which varies by bike. Confirm your bike on Robert Axle Project's online Axle Finder (robertaxleproject.com) before ordering, or bring your bike to the Tune Cycles workshop and we'll measure your existing axle and fit the replacement.

Robert Axle Project warrants its axles to be free from defects in material and workmanship for the lifetime of the original purchaser's ownership, covering manufacturing faults only — not misuse, crashes, incorrect installation or normal wear and tear. For warranty support, return the product to Tune Cycles and we'll manage the claim with Robert Axle Project's Australian distributor. This is in addition to your rights under the Australian Consumer Law, so keep your proof of purchase.
